Template Based Image Mosaics [chapter]

Yoon-Seok Choi, Bon-Ki Koo, Ji-Hyung Lee
2007 Lecture Notes in Computer Science  
Our approach controls overlap between tiles to minimize the gap by using the mask technique and adopts stackable technique to represent the fine detail of a source image automatically.  ...  Whenever a space is filled with tiles, the space of write mask which is corresponding to the filled space is set to 1. In order to minimize gap between tiles, the size of a tile can be reduced.  ...  The filling process is repeated until there is no space for tile filling.  ...
